How to Avoid Moisture Contamination When Mixing Bifasic Resin

Why Moisture Matters with Bifasic Resin

Even a small amount of water can react negatively with epoxy components, resulting in hazy or bubbly resin. This is especially important in the UK’s changeable climate, where humidity can inadvertently find its way into your workspace or materials. Maintaining a dry environment ensures a transparent and durable finish.

Practical Tips to Prevent Contamination

• Store resins and hardeners in sealed containers and keep them in a cool, dry place.
• Mix your resin in rooms with low humidity, using dehumidifiers in damp conditions where possible.
• Ensure all mixing tools and moulds are fully dry and free of condensation or leftover cleaning water.
• Wear gloves to prevent moisture and other contaminants from coming into contact with your mix.

Using easy-to-mix resins like the One-2-One epoxy resin can also simplify the process and minimise mishaps.

When This Matters Most

Avoiding moisture contamination is especially crucial when you’re aiming for clear jewellery, tabletops, or decorative items where any opacity will show. High-humidity days or environments with poor ventilation present increased risks—so extra vigilance pays off.
